WebDepending on the strength of the input signal, the output from the high Q stage may saturate the following input stage, driving it into its non-linear region and thereby creating distortion. Setting the gain of the high Q stage so that the peak at f 0 does not exceed 0dB results in a DC gain of less than 1 for the stage. http://www.seas.ucla.edu/brweb/papers/Journals/BR_SSCM_SPR_18.pdf
